getDefaultValue()

SourceRefLatticeValue llzk::SourceRefLattice::getDefaultValue ( SourceRefLattice::ValueTy v )

getSourceRef()

mlir::FailureOr< SourceRef > llzk::SourceRefLattice::getSourceRef ( mlir::Value val )

static

If val is the source of other values (i.e., a block argument, an allocation-like op result, or a constant), create the base reference to the val.

Otherwise, return failure. Our lattice values must originate from somewhere.
